Abstract

This article focuses on mountainous photovoltaic （PV） power stations as the research subject. An automated layout model for these power stations is developed based on the TIN algorithm for contour-to-grid terrain modeling, integrated with scanning line and terrain projection algorithms. Additionally, a shadow occlusion and power generation simulation model is constructed using the polygon （W-A） clipping algorithm and the Perez model. This study analyzes terrain data from a mountainous area in Chongqing, demonstrating that the automated layout algorithm effectively resolves the challenge of transforming the multi-faceted layout of triangular grids into a single-faceted layout. Furthermore, the proposed shadow occlusion, irradiance, and power generation models are compared with PVsyst simulation results. The maximum shadow occlusion error is 0.52%, the average irradiance error is 1%, and the annual power generation error is 0.83%. With a power generation deviation of less than 5%, the results indicate that the method presented in this study is highly accurate.
